Slick Slide

I need to make an animation involving 4 big pictures.
One is background, it is painted once static since then.
Two and three are right and left part of a drawing which slide towards each other(painted transparently while they do)
Four is a frame. It is drawn transparently over the sliding images.

Now to the problem. I do not know DirectX or ASM or stuff like that. So I implemented the drawing the way I knew(if you want I will put the procedure here). I succeeded to get rid of the flickering but the animation is still rather slow and ugly.

Please help me make it more presentable(If you saw the game starcraft you might know what I mean to do).

If you are moving TImages then put them on a TPanel...

no I am not moving images.
Here is my procedure roughly:

Procedure TMainForm.Animate;
var
i:integer;
bmp1,bmp2,Bmp3:Tbitmap;
J:TJPegImage;
Get:TResourceStream;
begin
Randomize;
...
//Slide Animation
bmp1:=TBitmap.Create;
bmp2:=TBitmap.Create;
bmp3:=TBitmap.Create;
J:=TJPEGImage.Create;

Get:=TResourceStream.Create(hInstance,'LEFT',RT_RCDATA);
bmp1.LoadFromStream(Get);
Get.Free;

Get:=TResourceStream.Create(hInstance,'RIGHT',RT_RCDATA);
bmp2.LoadFromStream(Get);
Get.Free;

Get:=TResourceStream.Create(hInstance,'FRAME',RT_RCDATA);
J.LoadFromStream(Get);
Get.Free;

bmp1.TransparentColor:=clWhite;
bmp1.TransparentMode:=tmFixed;
bmp1.Transparent:=True;
bmp2.TransparentColor:=clWhite;
bmp2.TransparentMode:=tmFixed;
bmp2.Transparent:=True;

FrameIMG.Canvas.Brush.Color:=clBlack;
FrameIMG.Canvas.CopyMode:=cmSrcCopy;
FrameIMG.Canvas.FillRect(Rect(0,0,FrameIMG.Width,FrameIMG.Height));
bmp3.TransparentColor:=clBlack;
bmp3.TransparentMode:=tmFixed;
bmp3.Transparent:=True;
bmp3.Height:=J.Height;
Bmp3.Width:=J.Width;

Bmp3.Canvas.Draw(0,0,J);
Get:=TResourceStream.Create(hInstance,'P'+IntTostr(Random(3)),RT_RCDATA);
J.LoadFromStream(Get);
Get.Free;
FrameImg.Canvas.Draw(28,28,J);
For i:=0 to 43 do
  begin
    // FrameIMG.Picture.Bitmap.Canvas.CopyRect(Rect(Width-i*16,28,Width-i*16+BMP2.Width,28+bmp2.Height),
      //                     BMP2.Canvas,Rect(0,0,BMP2.Width,bmp2.Height));
     FrameIMG.Picture.Bitmap.Canvas.Draw(Width-(i-4)*16,28,bmp2);
     FrameIMG.Picture.Bitmap.Canvas.Draw(-120+(i-4)*4,28,bmp1);
     FrameIMG.Picture.Bitmap.Canvas.Draw(0,0,bmp3);
     FrameIMG.Refresh;
  end;
bmp1.Free;
bmp2.Free;
bmp3.Free;
J.Free;
ShowCursor(True);
end;

You should be able to speed things up a bit by drawing onto a temporary bitmap (in memory) and then just throw that image at the screen once

i.e. Instead of drawing all four bitmaps to the screen each time in your loop, draw them to a temporary bitmap and then output THAT to the screen
